About this map

Settlements along the International Boundary define this northern Montana landscape, where the survey lines of Blaine and Phillips counties meet. This 1920 Army Corps of Engineers survey details a sprawling ranching and homesteading region organized around small post offices and school houses. Notable focal points include Caldwell P.O. near the border and Lost Lake P.O. further south. The map identifies specific schoolhouses like Schandelmeir S.H. and Woody Island S.H., which served as essential community anchors for isolated rural families. Water sources are critical features in this arid terrain, with Horse Shoe Lake, Island Creek, and the winding Dodson Creek providing the necessary drainage for the surrounding plains. Strategic triangulation points such as Betts, White, and Snow emphasize the precision of this military-led mapping effort during the early twentieth century.
